"When you contemplate the body by being within the body, you should not engage in all sorts of ideas about it; the same when you contemplate feelings by being within feelings, you should enter in without ideas; the same applies to contemplating the mind by being within the mind and contemplating thoughts by being within thoughts.

"The thoughts should be just the objects of mind and you should not apply yourself to any train of ideas connected with them. In this way, by putting ideas aside, your mind will become tranquil and fixed on one point. It will then enter into a meditation that is without discursive thought and is rapturous and joyful."

-Majjhima Nikaya
